COPENHAGEN, Oct 2 (Reuters) - Denmark has proposed a ban on the sale of new petrol and diesel cars from 2030 and hybrid from 2035, joining international efforts to promote electric-only vehicles to reduce air pollution and combat climate change.

The government has previously come under fire for increasing tax on electric cars in 2016, sending sales down from more than 3 percent of all new cars to almost zero, but now aims to follow the example being set in an increasing number of countries.

"It is a big ambition that will be hard to achieve. But that's exactly why we need to try," Danish Prime Minister Lars Lokke Rasmussen told parliament on Tuesday.

The plan requires parliamentray approval to become law and will be presented to parliament next week.

Britain and France have both pledged to ban new petrol and diesel cars from 2040 in move that could hit the wealth of oil producers and transform a car industry in which global carmakers are scrambling to adapt to the brave new world of electric vehicles.

In Sweden, sales of electric cars make up more than 7 percent of all new car sales while more than half of all new cars in Norway are electric or hybrid vehicles.

The mayors of Paris, Madrid, Mexico City and Athens have all said they plan to ban diesel vehicles from city centers by 2025, while the French government also aims to end the sale of new gasoline and diesel vehicles by 2040.

Denmark, the cradle of wind power, aims to become fossil fuel-free by 2050.

In 2017 Volvo became the first major traditional automaker to phase out vehicles powered solely by the internal combustion engine, announcing that all Volvo car models launched after 2019 would be electric or hybrids.
